Abstract
Treatment systems for treating flowable food products using electrical pulses to inactivate microbes. Systems described include one or more stages having flow-through processors. The flow-through processors have first and second electrodes which are spaced across a treatment chamber in which an intense electrical field is generated using bipolar electrical pulses. The treatment chamber is temperature stabilized to improve processing and minimize surface buildup on the electrodes. Oversized processor electrodes can be used such as in conjunction with an electrode spacer to provide a treatment zone having a relatively uniform and high electrical field strength.
